This paper presents a constraint management strategy based on ScalarReference Governors (SRG) to enforce output, state, and control constraints . The strategy, referred to as the Preview Reference Governor (PRG), can outperformSRG while maintaining the computational benefits of SRG . However, performance of PRG may suffer if large preview horizons are used . An extension ofPRG is proposed to remedy this issue . Quantitative comparisons between SRG, PRG, and Multi-horizon PRG on a vehicle rollover example are presented to illustratetheir performance and computation time .
